IN KING-ROLLER CONTROLLER.

Specification of Letters Patent.

Patented Feb. 17, 1920.

Application filed September 19, 1919. Serial No. 324,737.

To all whom t may concern.'

Be it known that 1, ELMER C. Srnivnn, a citizen of the United States7 residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in linking-Roller Controllers; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a fountain inking or semi-liquid supplying roller such as used in machines for printing addresses, or thelike, wherein the roller is hollow to contain the ink or pigment which is forced out through apertures in the periphery of the roller by means within the roller, when said mea-ns and said roller rotate relatively.

Such machines are provided with knobs which are held by the hand while the inking roller rotates so as to force the ink out of it. This is done from time to time to replenish the ink and it is necessary for the operator to use one hand for holding the knob of the inking roller until suiiicient ink has been supplied. This manipulation of the inking roller at intervals requires more or less time and attention and it is the object of the invention to provide means whereby the ink ejecting means can be held stationary while the inking roller rotates and then released.

1t is the obj ect of the invention to provide an inking roller controller of simple and inexpensive construction7 which can be readily applied to machines already in use as well as being capable of embodiment in new machines manufactured, and which will be operable in a convenient and efficient manner for controlling` the supply of ink in a more desirable and serviceable manner than by holding the knobs by hand.

TvVith the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts hereinafter described and claimed,it being understood that changes can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a fragmentary side elevation of an addressing machine showing the inksection through the inking ing roller and rollers which receive the ink therefrom.

F ig. 2 is an enlarged longitudinal vertical device, embodying the improvements.

Fig. 3 is a cross section taken on the line 3&3 of Fig. 2.

Fig. 4 is a sectional detail a modification.

|Machines, such as used for addressing envelops, letters and the like, and machines for other purposes are equipped with a fountain inking roller and the present improvements are useful with machines` embodying such an inking roller. As shown the improvements are used in a certain style of addressing machine, and the inking roller7 designated generally at 1, supplies ink to the roller 2 and thence to the drum 3. The remainder of the machine need not be con sidered, since the present invention relates only to the inking device.

The inking roller includes a cylindrical shell 4C having apertures scattered throughout its periphery through which the ink is forced from within the shell to supply ink to the roller 2, and the ends of the shell 4f are fitted upon heads 5 and G. The head 5 has a trunnion or journal 7 seated for rotation in a notch or seat 8 in the upper end of a supporting bracket 9 and a cotter pin 10 or the like extends through the bracket 9 above the trunnion 7 to prevent accidental lifting of the inking roller from the brackets. The trunnion 7 has a knob 11 which can be grasped by the hand for turning the inking roller or holding it still. The head 6 has an outer square boss 12 from which extends a trunnion or journal 13 which is seated for rotation in a notch or seat 14 in the upper end of the bracket 15, and a cotter pin 16 or the like extends through the bracket 15 above the trunnion 13 to hold it down in place. A tube 17 extends through the head 6 and its boss l2 and trunnion 13, and a funnel shaped knob 18 has a hub 19 secured on the outer end tube 17 by means of a set screw 20. An ink-ejecting member 21 is disposed within the roller and extends longitudinally along the interior of the shell 4, one end of said member 21 being secured, as at 22, to the inner end of the tube 17 and the other end of said member 2l having a pivot 23 engaging within the head 5, thereby mounting the roller and ink-ejecting member for relative illustrating portion of the A scribed serve to Vavoid holding either knob, and making it more convenient `and less rotation about a common axis. rEhe knob 18 has a removable plug 2stV therein closing the outer end of the tube 17, and permitting inl; to be introduced through said tube when the plug is removed. I

The foregoing structure is old in the art, and to supply ink to the roller 2 and drum 3, it is the practice to either hold the knob 1S while the roller 1 is in rotation so that the member 21 is stationary, thereby causing the ink to be squeezed out through the apertures, or the knobs 11 and 13 can' be rotated relatively by holding one of them and rotating the other, which will accomplish the same results. rlfhis, however, requires time and attention, taking the attention of the operator away from the normal operation of the machine, and sometimes interfering with the operation.

The. improvements which will be detrouble to control the ink supply.

In carrying out the invention. a device is employed for locking or latching one of the relatively rotatable parts oit the inlring roller against rotation while the other rotates, to thereby automatically supply the ink through the periphery or' the roller, and as soon as said` part is unlatched or released, the supply of ink will be stopped. As shown, the ink ejecting member 21 is held against rotation, and to accomplish this in a simple and etlicient manner, a collar 25 is fitted on the hub 19 of the knob 1S, and.

is provided with an annular outstanding flange 27V having a series of notches 23 therein. Said collar 25 has an aperture 26 to receive the set screw 20, whereby the collar will be held in place Without additional securing means. A latch or locking inger 29 is provided to engage the notches 28 for holding` the member 21 against rotation and this latch 29 has an apertured portion 30 to t snugly within the notch or slot 1a above the trunnion 13 on the pin or member 16.

The latch is thus pivotally mounted onV the pin 16, and the portion 30 can be grooved, as at 31, to lit over the trunnion 13. VThe latch 29 is thus pivoted Von the bracket 15 and can be swung to upright position as Vseen in full lines in Fig. 2, or it can be swung away from the inlring roller downwardlyinto one of thenotches 29 as seen in dotted lines. The latch 29 is so 'formed that when it is swung upwardly, the center ot gravity is at that side toward the roller, thereby supporting the latch in upright position, as it will have a tendency to swing away from the flange 27.

It is an easy matter to swing the latch or linger 29 downwardly so that it drops into one of the notches 28, which will therefore lock and hold the member 21 against rotation, while the roller continues to rotate.

' the shaft 35 of the roller 2.

drum 3 is relied upon for rotating the inling roller, gears can be used for positively driving the inking roller, to avoid slippage, at though the gears will not be required if the inling roller is already driven' positively,

so that there is no liability otl therroller slippingwhen the member 21 is latched. lLhus, a gear32 can be applied to the inhingroller, said gear having a square hole to receive the boss 12, vand said gear meshes with an idle pinion 34: mounted on in annular gear 36 is applied to the drum 3, and meshes withy the pinion 34e. This annular gear 36 has set screws 37 engaging within Vone end of the drum y 3 so as to rotate with said drinn, thereby driving the inlring roller and preventing samev from slipping when the latch 29 is thrown lin engagement with the 4liange 27.

As shown in Fig. 4t, it is also possible to cast the liange 27' integral with the hub 19 of the knob 18', said flange having the notches 28 'for the engagement 01"' the latch.

As a result oie this simple and inexpensive addition to the inlring roller, time and trouble is saved in inliing, and the opera-V ioo tion and output of the machine are enianced.

VThese improvements lcan also be used in a similar arrangement it the roller is used for -supplying paste or any other semiliquid. Y

'Having thus describedthe invention, what is claimed as new is Y 1. riihe combination of aY fountain inl; roller, kmeans therein Jfor discharging the ink, said means and roller being relatively rotatable, and means operable Jtor holding one of them against rotation Vand releasing same at will. A

2. rlhe combination oit a fountain inlr roller, means therein for discharging the ink, said means and roller being rotatable relatively, and means tor latching and un latching said means at will to hold it against rotation or release it. Y

3. The combination of a fountain inl; roller, ink discharging means therein, aV vnotched member rotatable with said means, and a latch movable into and out orV engagement with said member to hold said means against rotation and release it for rotation With said roller at will.

l. rlhe combination of a fountain inlr roller having a trunnion, a bracket support ing said trunnion, ink discharging means in the roller having a portion extending through said trunnion, a notched flange carried by said portion, and a latch pivotally mounted on said bracket to be moved by hand into and out of engagement with said flange to lock said means against rota tion and release 1t for rotation With the roller at Will.

In testimony whereof I have signed my name to this specification in the presence l5 H. C. HEYDEGGER.
